Streamline IIA Aluminum Propeller for Waydoo EVO | High-Efficiency eFoil Prop Upgrade

Perfect

Improved my range by at least 10% relative to the stock propeller, provides a smoother ride, and easier to regain control when starting to breach. A must have upgrade.

This propeller looks very nice and is working on my Waydoo EVO pro plus. There may be slight efficiency gains over the stock prop as claimed, I have not verified this. When I installed, it slipped on the shaft easier than the stock propeller with losser fit to the shaft which concerned me but I have had no issues with vibration, it seems the propeller nut holds and centers the propeller well. The only thing I would suggest for an improvement would be to add a nonmetallic shaft sleeve as steel to aluminum fit with prolonged exposure to salt water can cause galvanic corrosion. The current version works well and meets needs, I will use a special marine grade antisieze on the steel shaft and remove the propeller regularly to ensure it does not form aluminum oxide corrosion.
